Theory of Machine In a cam drive with uniform velocity follower, the sharp corners of the displacement diagram are rounded off at the beginning and at the end of each stroke. This is done In order to have acceleration in beginning and retardation at the end of stroke within the finite limits Because of loose contact of follower with cam surface Because the uniform velocity motion is a partial parabolic motion Because of difficulty in manufacturing cam profile In order to have acceleration in beginning and retardation at the end of stroke within the finite limits Because of loose contact of follower with cam surface Because the uniform velocity motion is a partial parabolic motion Because of difficulty in manufacturing cam profile ANSWER DOWNLOAD EXAMIANS APP

Theory of Machine The two links OA and OB are connected by a pin joint at O. If the link OA turns with angular velocity ω₁ rad/s in the clockwise direction and the link OB turns with angular velocity ω₂ rad/s in the clockwise direction, then the rubbing velocity at the pin joint O is (where r = Radius of the pin at O) (ω₁ - ω₂)2r (ω₁ + ω₂)r (ω₁ - ω₂)r ω₁.ω₂.r (ω₁ - ω₂)2r (ω₁ + ω₂)r (ω₁ - ω₂)r ω₁.ω₂.r ANSWER DOWNLOAD EXAMIANS APP
